MAGAZINE scRnw DRIVER. ,l

Application led January 20, 1922. Serial No. 530,589.

To all 'whom it may concern." v

Be it known that I, HENRYSIMON, a citizen of the United States, residingat Santa Ana, in the county of Orange and State of California, haveinvented a new and useful Improvement in Magazine Screw Drivers, ofwhich the following is a specification;V

This invention has referencetomultiple tools, and more particularly tomultiple screw drivers, although the invention `nay be applied tocertain other types of multiple tools, but for simplicity, thedescription will be limited to a multiple screw driver, withoutnecessarily being confined thereto.

In accordance with the invention, there is provided a handle ofappropriate size, in which there is housed a plurality of screw driverbla-des, preferably of different vsizes or specically differentcapacities, and so arranged that a chosen one of the blades may beprojected from the handle or housing into position for use, to theexclusion of the other blade or blades, and the chosen blade is thereclamped or locked against retraction into the housing. The-projectedblade may be subsequently retracted and the second blade be similarlyprojected and clamped, with- ,out either blade interfering with theother blade, or there being any danger of loss of either blade.

Besides the casing vand the blades, the screw driver structure includesa magazine or change-shell, in which the blades may be stored andshifted at will to bring one or the otherjof the blades into the centerline of the casing. When the parts are appropriately assembled, and oneofthe blades is projected, the projected blade is clamped in theprojected position and the other blade is at the same time housed in themagazine in the retracted position, and cannot then move more than aminimum distance lengthwise of the magazine. Y

The construction of the tool is such that the blades may be shiftedlaterally, one at a time, solely by gravity, while the blade which isnot projected cooperates to guide the blade, which is projected, intooperative or working position and back again into the handle of thescrew driver. j

The screw driver body or -casing is provided atone end'with a chuckhaving split jaws and a screw sleeve, through which either one of thescrew-driver blades may extend, with .the blade having a butt end toolarge to pass through the chuck, and the shank of the blade is smallenoughin diameter to pass through such jaw. The

.clutch sleevemay be manipulated to clamp the split jaw upon the shankof the blade so tightly as to hold the projected bladeagainst anyliability of the clamped blade being lretracted' by any force to whichthe blade is` s subjected when in use. i i

Thev inventiony will be Vbest understood from a consideration ofthefollowing detailer description taken in connection with the accompanyingdrawing forming part of this spe-cication, with the understanding,howeverythat the invention isnot confined 7o i `to any strict conformitywith theshowing of the drawing, but may be changed and' modified so longas such changes and modiiications markno material departureffr'om -thesalient featureszof the 'invention as ex'- pressed in the appendedclaims@ j In the drawing Q "Fig l is anelevaticnof-'a screw driver.embodying the invention.

The handle-or casing lv` is designed to house appropriate screw-drivervblades 2,

which may be convenientlyvformed of bar steel. In the drawing,

3. The blade end 5 terminates ina tapered extremity 6,` designed toentera ,screw kerf when the screw-driver blade 'is projected.

` Fixed to the innerwall of the handle ory substantially elliptical formthough not necj each'blade is provided with a butt end 3, ashanlrportion 4,

VIt is necessary/,"however, Ythat itsdiameter shouldbe greaterfin one' direction 'than the other, and thatitsleastl diameter should ber justk sutiieient'to'receive the screw housingl is a change-shell or magazine 7 of y multaneously laterally of thehandle byA gravity andprojectable also by gravity one at a timelengthwise ,through the longitudinal center line of the magazine, saidhandle having at its outer end a clutch provided with a passage on suchcenter line and. operable to clamp the screw-driver blade in theprojected position.

5. A magazine screw driver or other like tool, comprising a hollowhandle with an elongated flattened elliptical-shaped magazine of a sizeto contain two blades side by side in contact with each other and leaveroom for their lateral movement in one direction only, said blades beingfree to move laterally under the action of gravity, and movable one at atime lengthwise of .the magazine and handle also by gravity, and aclutch and manipulating means therefor at the forward end of the handleprovided with a passage on such center line to grip a projected bladewhenextended beyond the clutch.

6. A magazine screw driver or other like tool, comprising an elongatedhollow handle, with a longitudinally extended magazine therein, saidmagazine being of elliptical cross section having a width in onedirection to accommodate two screw-driver blades in side by sidecontact, and a width in the other direction which constrains the bladesfrom movement in that direction, and a clutch at the forward end of thehandle and having a through passage located in the longitudinal centerline thereof, said clutch having a clamping sleeve to compress theclutch onto a projected blade which is passed through the chuck from theinside. l

7. A magazine screw driver or other like tool, comprising a hollowhandle with a fixed magazine centralized therein and ilattened intoelliptical form to accommodate two blades lengthwise of the handle inside engagement and tol contact sidewise and crosswise of the handle, tolocate either blade in the longitudinal center line of the handle,A theforward end of the magazine being open and said opening being on suchcenter line, whereby either blade may be caused to project individuallythrough the front end of the handle and be held in the projectedposition.

8. A magazine screw driver or other like tool, comprising a hollowhandle with an elliptical-shaped magazine located centrally therein,said magazine extending from side to side of the handle and secured tothe inner walls of the handle, and the fiat sides of the magazine beingspaced from the corresponding sides of the handle, a clutch at theforward end of the handle provided with a. through passage on thelongitudinal center line of the handle, said forward end beingcontracted, and the forward end of the magazine terminating at thecontracted portion, and a pair of screw-driver blades normally housed inthe magazine, and said blades being located to gravitate in the magazineinto side by side relation, with a chosen one of the blades in line withthe clutch for projection therethrough by gravity and there held by theclutch against retraction.

In testimony that I claim the foregoing as my own, I have hereto aiiXedmy signature.
